Re: [SQL] SELECT across two databases

PostgreSQL does not support this feature at this time. And, I would not
expect it any time soon. You would have to either code such a join by
hand.

There is one other option. Many ODBC compliant tools will support
multi-data source joins. However this solution may perform poorly
because one side of the join may iteratively query one of the data
sources. Your call.
